水流指示器

GD2000型水流指示器设计原理及应用

Design principle and application of water flow indicator GD 2000

实践证明，新型水流指示器指示清楚、密封性好、转动灵敏。

Practice proved that the indication of the new water flow indicator is legible , its watertightness is good , and its rotation is free .

下一步，但仍是固定的她不作大的灌肠，与一个明确的袋、大型的塑胶喷嘴和水流指示器；

Next , while still immobilized , she is given a large enema , with a clear bag , a large plastic nozzle and a flow indicator ;

经营范围有水系统类：消火栓箱系统，各种水泵接合器，室内外消火栓，湿式报警阀，水流指示器，喷淋头。

Operating range of water systems categories : fire box system , a variety of pump adapter , indoor and outdoor fire hydrant , wet alarm valve , water flow indicator , sprinkler head .

本文结合工程实践对自动喷水灭火系统设计流量确定、选泵、湿式报警阀设置位置、水流指示器、信号阀的设置提出一些看法。

Some problems in automatic sprinkling system design such as the determination of design flowrate , selection of pumping equipments , fix of the locations of wet alarm valves and setup of water flow indicators and signal valves are discussed .

下一步，仍然固定的同时，她是一个大灌肠，具有明显的包，一个大塑料喷头和水流指示器，她别无选择，只能浸泡，最后一滴！

Next , while still immobilized , she is given a large enema , with a clear bag , a large plastic nozzle and a flow indicator ; she has no choice but to soak it up to the last drop !
